Relationships between components of blood pressure and cardiovascular events in patients with stable coronary artery disease and hypertension

Observational studies have shown a J-shaped relationship between diastolic blood pressure (BP) and cardiovascular events in hypertensive patients with coronary artery disease. We investigated whether the increased risk associated with low diastolic BP reflects elevated pulse pressure (PP). In 22 672 hypertensive patients with coronary artery disease from the CLARIFY registry (Prospective Observational Longitudinal Registry of Patients With Stable Coronary Artery Disease), followed for a median of 5.0 years, BP was measured annually and averaged. The relationships between PP and diastolic BP, alone or combined, and the primary composite outcome (cardiovascular death or myocardial infarction) were analyzed using multivariable Cox proportional hazards models. Adjusted hazard ratios for the primary outcome were 1.62 (95% confidence interval [CI], 1.40–1.87), 1.00 (ref), 1.07 (95% CI, 0.94–1.21), 1.54 (95% CI, 1.32–1.79), and 2.34 (95% CI, 1.95–2.81) for PP<45, 45 to 54 (reference), 55 to 64, 65 to 74, and ≥75 mm Hg, respectively, and 1.50 (95% CI, 1.31–1.72), 1.00 (reference), and 1.58 (95% CI, 1.42–1.77) for diastolic BPs of <70, 70 to 79 (ref), and ≥80 mm Hg, respectively. In a cross-classification analysis between diastolic BP and PP, the relationship between diastolic BP and the primary outcome remained J-shaped when the analysis was restricted to patients with the lowest-risk PP (45–64 mm Hg), with adjusted hazard ratios of 1.53 (95% CI, 1.27–1.83), 1.00 (ref), and 1.54 (95% CI, 1.34–1.75) in the <70, 70 to 79 (reference), and ≥80 mm Hg subgroups, respectively. The J-shaped relationship between diastolic BP and cardiovascular events in hypertensive patients with coronary artery disease persists in patients within the lowest-risk PP range and is therefore unlikely to be solely the consequence of an increased PP reflecting advanced vascular disease

Folk Theory of Mind: Conceptual Foundations of Social Cognition

The human ability to represent, conceptualize, and reason about mind and behavior is one of the greatest achievements of human evolution and is made possible by a “folk theory of mind” — a sophisticated conceptual framework that relates different mental states to each other and connects them to behavior. This chapter examines the nature and elements of this framework and its central functions for social cognition. As a conceptual framework, the folk theory of mind operates prior to any particular conscious or unconscious cognition and provides the “framing” or interpretation of that cognition. Central to this framing is the concept of intentionality, which distinguishes intentional action (caused by the agent’s intention and decision) from unintentional behavior (caused by internal or external events without the intervention of the agent’s decision). A second important distinction separates publicly observable from publicly unobservable (i.e., mental) events. Together, the two distinctions define the kinds of events in social interaction that people attend to, wonder about, and try to explain. A special focus of this chapter is the powerful tool of behavior explanation, which relies on the folk theory of mind but is also intimately tied to social demands and to the perceiver’s social goals. A full understanding of social cognition must consider the folk theory of mind as the conceptual underpinning of all (conscious and unconscious) perception and thinking about the social world

The Effect of Neighbourhood Housing Tenure Mix on Labour Market Outcomes: A Longitudinal Perspective

This paper investigates the effect of different levels of neighbourhood housing tenure mix on transitions from unemployment to employment and the probability of staying in employment for those with a job. We used individual level data from the Scottish Longitudinal Study (SLS), a 5.3% sample of the Scottish population, covering a 10 year period. We found a strong negative correlation between living in deprived neighbourhoods and labour market outcomes (getting or keeping a job). We found a small, but significant, positive correlation between living in mixed tenure (40-80% social housing) streets and transitions from unemployment to employment. In the conclusion we discuss the extent to which we think these results can be interpreted as 'neighbourhood effects' or selection effects.tenure mix, neighbourhood effects, labour market transitions, deprivation, longitudinal data, Scotland

System-wide impacts of hospital payment reforms : evidence from central and eastern Europe and central Asia

Although there is broad agreement that the way that health care providers are paid affects their performance, the empirical literature on the impacts of provider payment reforms is surprisingly thin. During the 1990s and early 2000s, many European and Central Asian countries shifted from paying hospitals through historical budgets to fee-for-service or patient-based-payment methods (mostly variants of diagnosis-related groups). Using panel data on 28 countries over the period 1990-2004, the authors of this study exploit the phased shift from historical budgets to explore aggregate impacts on hospital throughput, national health spending, and mortality from causes amenable to medical care. They use a regression version of difference-in-differences and two variants that relax the difference-in-differences parallel trends assumption. The results show that fee-for-service and patient-based-payment methods both increased national health spending, including private (out-of-pocket) spending. However, they had different effects on inpatient admissions (fee-for-service increased them; patient-based-payment had no effect), and average length of stay (fee-for-service had no effect; patient-based-payment reduced it). Of the two methods, only patient-based-payment appears to have had any beneficial effect on"amenable mortality,"but there were significant impacts for only a couple of causes of death, and not in all model specifications.Health Monitoring&Evaluation,Health Systems Development&Reform,Health Economics&Finance,Health Law,Population Policies

Tracing Mobile Inventors – The Causality between Inventor Mobility and Inventor Productivity

This paper analyzes the causality between inventor productivity and inventor mobility. The results show that the level of education has no influence on inventor productivity. Making use of external sources of knowledge, on the contrary, has a significant effect on productivity. Finally, firm size has a positive impact on productivity. Firm size also influences inventor mobility, although negatively. Whereas existing research implicitly assumes causality to point in one direction, this study ex-ante allows for a simultaneous relationship. To deal with the expected endogeneity problem, instrumental variables techniques will be employed. Results show that mobile inventors are more than four times as productive as non-movers. Whereas mobility increases productivity, an increase in productivity decreases the number of moves

Socio-economic status and physical health outcomes : the need for change in theoretical formulations : thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University

The Black Report (Department of Health and Social Security, 1980) , which was a seminal publication in the field of health inequality, proposed several possible theoretical explanations for the phenomenon of socio-economic health inequality. To date the models proposed in the Black Report have yet to be improved on, or developed greatly. While research in the field of socio-economic health inequality has been substantial, the state of theoretical formulation which attempts to explain such inequality has remained static. The phenomenon of socio- economic health inequality will be established by producing evidence for how socio-economic status impacts on health from many countries, but especially from the United Kingdom, North America, Australasia, and Europe. Potential pathways for socio-economic status to impact on health outcomes will be assessed, and an illustration of potential pathways will be provided with an application. The theoretical approaches of the Black Report, along with a more recent conceptualisation, will be discussed. The potential contribution of psychological factors to socio-economic health inequality will be considered following the establishment of the relationship, proposal of potential pathways, and theoretical formulation discussions to demonstrate how such factors are involved in socio-economic health inequality. From these first four sections it can be deduced that current theoretical formulations to explain socio-economic health inequality are deficient. To contend with this deficiency it is proposed that a more holistic approach, which includes psychological factors, is necessary. Future research should seek to empirically validate links within the confines of a more holistic framework if our understanding of the relation between socio-economic status and physical health outcomes is to improve
